I believe that many partners in the use of micro switch, will encounter some problems, because the basic knowledge of micro switch is not very understanding, many people do not know how to deal with, but for ordinary problems, we can solve them. Below I will explain to you what common problems will be encountered in the use of micro switch? How to solve it? Let's get a look at it together.
1. What is the cause of poor contact of microswitch? How to deal with it?
The first possibility is adhesion dust such as copper sheet and switch contact point, and it is recommended to use a sealed electrical switch.
The second is due to the damage of harmful gases in the atmosphere, resulting in the formation of a thin film with insulation characteristics on the surface of the joint, it is recommended to use joint raw materials with good natural environment adaptability (gold, aluminum alloy, etc.)
2. Even if the micro switch is pressed, what is the reason why the load does not open?
There are many reasons, one is because of poor contact, two is because of the loose connection, three is because the internal torsion spring is damaged, four is because of the different speed of operation, five is because of the frequent work, six is because of garbage, dust and other reasons.
3.Micro switch insulation aging ablation? how to prevent it?
First of all, the main reason for the aging and corrosion of the microswitch is that the load is too large, which generates the electric arc and makes it float around. This problem can be solved by the switching load of the vehicle relay and AC contactor.
Secondly, because the surrounding air humidity is too large, the surrounding temperature has significantly changed, making the water droplets in the air permeate, and the degree of carbonization of the insulation layer increases. In wet and cold environments, the use of micro switches for a long time should be avoided, or closed switches should be used.
